keep the upper rack 36 from 'rotating and itsA

Y
„
The inrushing warm air whichenters the ifa-_
frigerating chamber I4 when the cover I3 isre 60
moved from the Aopening `I2 carries considerable ¿
moisture which has a tendency to condense and
form frost on the cold inner surfaces I5 and I6
thereof. These frost lformations, while slow- in
forming, would eventually build up to a depth 65
capable of freezing the 'racks'30 and 36 to theA
sides I5 and bottom I6 of the >chamber lI4-so
wi-thin the cabinet, but since frost acts asl insula-- i
tion and decreases the eiliciency ofthe unit, it- is
frequently desirable toremove it erítirely from the'
surface I5 of the chamber» I4. This maybe best
accomplished by the blade 60.y When both means i»
are employed, the cabinet will operate indefinite- 1
ly without danger of _the racks freezing therein, Y
and with `good efñciency; Itis quite-apparentV
that only one o! the frost removing'means‘may
bedesirable in some instances.- >Either-means forV
removing frost from the'surfaces of the chamber
is suiiicient to elimnate the usual weekly defrost#
ing'and .to keep'the racks free4 for rotation vin
the cabinet for relatively long periods of time. '
Although I -have only.descrìbed in detail sev# “
eral vforms of the invention, itwill be readily’
that they may not be operated until the >cabinet
is entirely defrosted. These inherent ,disadvan
